I think the Nikon will be a better action photography performer. The auto focus will be better and I think it will be just a bit quicker as far as the shutter response goes. I do like the E-510's built-in image stabilization. It will be a better low light shooter because of the image stabilization. And any DSLR is going to be way better than any point-and-shoot you've ever had. But I think the Nikon's better AF will increase your soccer photo success rate.
